EGG AND CREAM WHIPPER.

Specification of Letters Patent.

Patented Feb. 6, 19173.

Application filed April 6, 1916. Serial No. 89,422.

To all whom it may concern:

Be it known that I, FREDERICK STONE USHER, a citizen of the United States, residing at Indiana Harbor, in the county of Lake and State of Indiana, have invented certain new and useful Improvements in Egg and Cream Whippers, of which the following'is a specification.

This invention relates to improvements in egg boaters, cream whippers, and similar devices, and has for one of its objects to improve the construction and increase the efliciency and utility of devices of this character.

Another object of the invention is to provide a simply constructed device whereby a two-fold action is produced upon the cream or other product without materially increasing the force necessary to operate the device.

With these and other objects in view, the invention consists in certain novel features of construction, as hereinafter shown and described and then specifically pointed out in the claims; and in the drawings illustrative of the preferred embodiment of the invention Figure 1 is a side elevation of the in1- proved device;

Fig. 2 is a transverse section on the line 2-2 of Fig. 1;

Fig. 3 is a perspective view from beneath of the combined transverse connecting member and support for the frame and operating mechanism;

Figs. 1 and 5 are views of the blanks from which the member shown in Fig. 3 is constructed.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The improved device comprises in general a supporting frame including spaced sides, a connecting device at the upperend of the frame, beater devices operating within the frame, andmeans for actuating thebeater devices.

The frame portion of the device is constructed from two sections of material, preferably heavy wire twisted together, as shown at 10, near their ends with the shorter portions bent first vertically for a short distance, as shown at 1112, and thence curved in opposite directions, as shown at 13-14. The longer portions of the frame members are first curved in opposite directions, as

represented at 1516, and extending substantially in parallel relations to the portions 1314, and thence directed vertically in parallel relations, as shown at 1718, the portions 17-18 forming the sides of the supporting frame.

At their upper ends the side members 1718 are united by a transverse connecting device initially formed from plates of sheet metal and cut in the form shown in Figs. 4: and 5. The portion illustrated in Fig. 5 includes a central body portion 19 which forms the top of the connecting device, laterally directed portions 20 which form the sides of the connecting device and end portions 21 which form the ends of the connecting de .vice. The end portions 21 are of greater length than the lateral portions 20, as shown in Fig. 5. To construct the connecting device the side portions 20 are bent at right angles to the body 19 along the dotted lines 22 and the edges of the portions 20 likewise bent at right angles to the portions 20 along the dotted lines 23 to form guide ledges or flanges 24, as shown in Fig. 3. The terminals 21 are first bent at right angles to the body 19 along the dotted lines 25 and the outer portions of the ends bent at right angles along the dotted lines 26 and the terminals of the ends bent over along the dotted lines 27 to form channels 28, as indicated in Fig. 3. By this means the portions which are bent at right angles along the lines 26 extend in parallel relation with the longitudinal plane of the connecting device so that the turned over portions 2 1 and 28 serve as ribs to support a base plate 29. When thus assembled a box-like structure is produced with projections at the ends, as shown in Figs. 1 and 3. The base 29 and the end extensions of the connecting member are pierced to receive the upper ends of the side members 1718 of the frame, the terminals of the side members being bent or clenched over the projecting portions of the connecting device, as illustrated at 30 in Fig. 1. By this means the frame members coact with the twisted portions 10 and the connecting device to produce a rigid frame or support including the curved portions 1314 and 1516.

The heater mechanism of'the improved device comprises coactingreversely twisted members 31-32 pivoted at their upper ends, as represented at 3334 in the base portion 29 of the connecting member, and extending between the side portions 1718 and in parallel relation thereto and bent into hoop-like terminals 3536 at their lower ends. The members 353(3 form the heaters of the improved device and are mounted to rotate upon the vertical portions 1112 of the frame, as shown in Fig. 1. The beater member 35 thus rotates between the .inner frame portion 13 and the outer frame portion 15, while the beater member 36 rotates between the inner frame portion 1e and the outer frame portion 16. The members 3132 being twisted in opposite directions will likewise rotate in opposite directions, as hereafter explained, and thus cause the sides of the beater members to alternately pass between the spaced frame portions 1315 and 14t16. The beater members 35-36 are so mounted and operated that they alternately rotate one within the other without coming in contact, as will be obvious.

Movable vertically through suitable apertures in the top 19 and the base 29 of the connecting device is an operating rod including a main body portion 37 terminating in a hand grip 38 at the upper end and bent into lateral loops 39 l0 at the lower ends, the loops being fiat and engaging around the twisted members 31-32, as illustrated in Fig. 2. The loops 394[0 fit with suliicient looseness around the twisted membcrs to cause the loops to rapidly rotate the twisted members when the rod is moved vertically. Thus when the rod is moved clownwardly the twisted member 31 will be moved in one direction and the twisted member 32 will be moved in the opposite direction, and

then when the rod is moved upwardly the twisted members will be reversed in movement, as will be obvious. A spring 41 is connected at its upper end to the base member 29 of the connecting device and at its lower end to the transverse portion of the rod, so that when the rod is moved downwardly the spring will be distended and when the rod is released the spring by its reaction will return the loops 39'l0, together with the rod, to their upper position. The member 31 and the hoop-like beater member 35 are constructed from a sheet of metal of suitable width and the terminal of the beater 35 soldered, brazed, electrically welded, or otherwise attached, as illustrated at 43, while the twisted member 32 and the beater 36 are in one single piece with the terminal suitably attached, as shown at 44.

The members 13-15 coact with the beater 35, while the similar members 1-116 coact with the beater 36, the portions l3-14 materially increasing the action and correspondingly decreasing the time required to produce the desired results.

A stop 4-5 is arranged upon the rod 37 to engage the connecting member to limit its downward movement, the stop being preferably formed by extending the terminal of the rod 37 and twisting it around the body of the rod, as shown in Fig. 1. By this means the hand grip 38 is limited in'its downward movement to prevent the fingers of the operator from being pinched against the connecting member. -The stop also prevents the spring tl being unduly stretched, and prevents the members 40 from striking the joints 43 and 44:.

The improved device is simple in construction, is constructed wholly of metal and is strong and durable and operates effectually for the purposes described.

Having thus described the invention, what is claimed as new is:

1.

In testimony whereof I affix my signature.
